IMPROVEMENT IN STEAM'FIRE-ESCAPES.

v Specification forming part of Letters Patent No. 178,271, dated August22, 1874.

To alt whom it, may concern;

Be it known that I, J AMEsGnADDERToN, of Brooklyn, in the county ofKings and State of New York, have invented an Improvement inCombinedFire Escape and Extinguishers, of which the following is aspecication:

My invention comprises the combination, in an organized machine, of asystem of lazytongs carrying a suitable platform, a steam' engine orequivalent motor, connecting with the lazy-tongs by appropriate gearing,and a pump or pumps, worked by the engine, and provided with a hosesection or sections, attached to or elevated by the movement of thelazy-ton gs, the whole constructed and arranged to serve the doublepurpose of a steam tire-escape and a steam fire-engine at one and thesame time. v

Figure l is a side View of an apparatus constructed according to myinvention.- Fig. 2 is a vertical longitudinal section, and Fig. 3 is aplan View, of the same.

The system of lazy-tongs is represented at A, the lower orsupporting'pivot or shaft thereof being shown at e. The lowermost of thesuperposed levers constituting the lazytongs have pivoted to 'theirouter extremities the toothed sectors B, which lap past each other, andgear into pinions C, which said pinions gear into each other, all asshown in Fig. 2.

The shafts b of the pinions G extend through their bearin gs in thesides of the wheeled supporting-frame D, their projecting ends being'furnished with pinions E. At each side of the aforesaid frame is avertical worm, B, provided between and gearing with the pinions E, andfurnished with a bevel-gear, F, which latter gears into a similarbevelwheel, G. The bevelwheels Gr are provided upon the ends of atransverse shaft, c, which is journaled in suitable bearings in theframe D, and has, furthermore, another bevel-wheel, H, the purpose ofwhich is hereinafter fully set forth.

At the top of the system of lazy-tongs is a horizontal platform, I. Oneend of this platform is pivoted fast to the adjacent portion of thelazy-tongs, but the other simply rests upon a transverse bar, d,provided to the lazy-tongs in such manner that, during the narrowing ofthe latter in the elevation of the platform, the

June 6,1876; application med v said platform may slide or move upon thebar d without binding.

J is the boiler of a steam-engine, the cylinders Aof which are shown atK, and which, through suitable piston-rods af, cranks c', pulleys e',band j", 86e., give rotary motion to a shaft, f, which shaft f carries abevel-pinion, g. A shaft, M, has at one end a bevel-pinion, m, gearinginto the pinion g, and at the other a like pinion, n, gearing into thebevel-wheel H. The working of the engine, therefore, rotating the shaftM, gives vmotion to the shaft 4c,and thence through bevel-wheels Gr andF, worms B', spur-pinions E, spur-wheels C, and sectors B, to draw thelatter inward to raise the lazy-tongs, or thrust them outward tolowinone direction or the other, by reversing the engine, or by any othersuitable agency.

The bevel-pinion g is capable of a longitudinal movement upon the shaftf, and is con nected with a shipper, r, whereby it may be moved into orout of gear with the pinion m, the said shipper being provided in itsAunder side with notches, catching upon a shoulder or stud at g', tohold the aforesaid pinion gin position, in gear or out of gear, as thecase may be, with the pinion m. required, when the lazy-tongs have beenelevated to the required height, the latter are held against descent bythe locking action of the worms B' against the reverse movement of thespur-pinions E. Any desired form or construction of steam boiler orengine may be used, or an air-en gine or other equivalent motor may beused in place of the steam-engine. The gearing whereby the engine isconnected with the system" of lazytongs may also be modified in variousways Without affecting the principle of my invention.

At one end of the wheeled frame D may be ,provided a reel, L, carrying aeixible ladder,

tached to the platform l, the ladder being wound from the reel as theplatform is raised, and aording a means of ascent to orI descent fromthe aforesaid platform when elevated.

P l?Y are pumps, the plungers of which are 'worked by rods u, connectingto .the cranks c',

actuated by the engine, as hereinbefore `set er the same, according asthe shaft j' is moved When out of gear, as l o, the upper or outerextremity of which is atl forth.. Q is the air-chamber ofthe pumps, andR the outlet, -to which are attached the hosesections S, the inlet tothe pumps being shown at T. i To this inlet, when the apparatus is inuse, should be attached a hose or pipe, extending to a hydrant or othersuitable source of water-supply.

The hose-section S is attached at intervals tothe lazy-tongs, as shownin Figs. l and 2, its upper end portion being furnished with the usualnozzle r', and left loose and ilexible, so as to be turned in anydirection, at the option of the reman managing the same, and standingupon the platform I. I

Instead ot' plunger-pumps', rotary pumps may be used, and the mechanismby which they are connected with the engine may, when desired, be modiedin various Ways Without affecting the modus operandi of the apparatus.

The several essential parts ot' the machine bein g thus combined,organized, and arranged, the operation of the engine elevates thelazyvtongs, thereby raising` the platform to bring the fireman standingupon it, and the hosesections manipulated by such fireman, in properrelation to the burning building to permit the most efficient play ofwater upon the flames, and simultaneous with this the same motive powerthat thus actuates the lazytongs operates the pumps to force water vthrough the aforesaid hose-sections, to provide for the just-mentionedplay of water upon the Haines; this elevation ot' the lazy tongs andpower -pressure, and projection of water Q y W www through thehose-sections, enabling the platform-to be brought sufciently near thewindows of upper ystories to permit the' escape of persons therefrom tothe said platform while the ames are being fought back from the Vicinityofthe latter by the jets, steam propelled, as just mentioned, from thehose section or sections, for, when preferred, two or more suchsections, or only one, may be employed.

lt will be understood that the operation of the pumps and lazy-tongs,and their respective adjuncts, is alike simultaneous whether thelazy-tongs are in upward movementl or stationary in their elevatedposition,this lastnamed position of the lazyton gs being that in whichthey are available for the escape of persons from high Windows, and inwhich they enable the jets propelled from the steam-driven pumps to bemost advantageously directed against the tlames.

What I claim as my invention is- 'lhe combination, `in an organizedmachine, ofthe lazy-tongs, tremens elevating-platform, and a steammotorconnected therewith by suitable gearing to operate the same, said'steam-motor being also adapted, by means of a force pump or pumps andhose-connections, to serve as a lire-engine, substantially as described.
